    FIELD OF THE INVENTION
    The invention relates to a system for simultaneously blowing and filling preformed plastic containers. BACKGROUND
    Plastic containers like water bottles are manufactured and filled according to different methods, including blow molding or stretch blow molding.
    According to one of these known methods, a plastic preform is first manufactured using a molding process and then heated before being placed inside a blow mold.
    The preform usually takes the form of a cylindrical tube closed at its bottom end and open at its opposite end.
    Once the preform has been positioned in the mold, only the open end of the preform is visible from above the mold.
    This method makes use of a drawing rod which is engaged downwardly at the open end of the preform so as to abut its closed bottom end. The drawing rod is additionally driven to be pushed against the closed end, thereby resulting in the drawing of the preform.
    After the stretching phase has started, a liquid is also injected in the preform through its open end as disclosed, for example, in the patent of Depositor EP 1 529 620 B1. This injection of liquid causes the preform to expand until it comes into contact with the inner walls of the mold, thereby reaching the final shape of the bottle.
    Until now, a machine or system known for simultaneously blowing and filling plastic containers is vertically oriented and manufactures one container at a time.
    Each machine or system comprises a mold that closes a preform, drawing means for drawing the preform into the mold and injection means for injecting a liquid under pressure into the preform to cause the expansion of said preform into the mold .
    However, the operational productivity of such a machine that operates according to the above manufacturing process is limited.
    There is, therefore, a need to have a system to manufacture and fill containers with high operational productivity. SUMMARY OF THE INVENTION
    In this sense, the invention provides a system as defined by claim 1.
    The rotating apparatus is then equipped with a plurality of rotating stations that are operable to blow and fill a plurality of containers at the same time while the prior art machine only blows and fills one container at a time.
    Each rotating station in the invention includes a mold, drawing means and injection means.
    It should be noted that the prior art machine uses a preferably heavy mold and involves a manufacturing process in which a container is simultaneously blown using a movable stretch rod and filled with liquid supplied from the outside.
    Taking into account the above, it seems quite natural for the person skilled in the art to keep such a machine in a fixed position, notably due to the weight of the mold and the supply of liquid to be injected.
    In view of these technical difficulties, the design of a rotary apparatus with a plurality of rotary blowing and filling stations connected to a common rotary distributor to deliver liquid to the stations is, therefore, the result of an inventive step.
    The system according to the invention dramatically increases the operational productivity of a conventional device or machine as briefly described above.
    The device rotates with the moving masses of liquid, which are distributed to the different injection media. Surprisingly, injecting a liquid during the rotation of the device does not give rise to any mechanical or fluid problems contrary to what would be expected by the person skilled in the art.
    According to a possible characteristic, the pump device is part of the rotating apparatus and, in a particular embodiment, the rotating distributor.
    Thus, each component of the system to simultaneously blow and fill plastic containers rotates.
    According to another possible alternative feature, the pump device is in a fixed position while the device including the molds, drawing means, injection means and dispenser rotates.
    This arrangement makes it possible to lighten the weight of the rotating part of the system and, therefore, make its structure simpler.
    Placing the pump device outside the rotating part of the system also makes it possible to simplify the rotating electrical connection between the fixed and moving parts. In particular, this swiveling electrical connection does not require any dedicated power supply cable for the pump device.
    Such a rotating electrical connection is, however, necessary to supply power to different pieces of equipment such as solenoid valves, etc.
    According to a possible characteristic, the plurality of molds is spatially arranged around the periphery of the distributor.
    This arrangement is particularly simple and makes it possible to easily distribute the pressurized liquid radially to the periphery of the distributor, which corresponds to the natural movement of a fluid in a rotating device.
    According to another possible characteristic, the distributor is rotatable around a central vertical geometric axis, with each mold having an upper part that is provided with an opening, each preform has a mouth that is arranged in said opening when included in said mold, said opening is centered around a longitudinal geometric axis which is inclined towards said central vertical geometric axis.
    This arrangement makes it possible to avoid excessive spillage of the liquid contained in each rotating preform after it has been injected into it.
    This inclination takes into account the natural movement of a liquid in a rotating device that is pushed radially and externally by the action of centrifugal forces. Thus, contrary to what the person skilled in the art would expect the injection of liquid in the preforms during their rotation does not lead to the splash of the liquid around all the preforms thanks to the above provision.
    It should be noted that each of the plurality of molds, drawing means and injection means, is inclined to said central vertical geometric axis around the periphery of the dispenser.
    According to a more specific characteristic possible, said inclined longitudinal geometric axis is at an angle to the vertical geometric axis that is greater than 0 ° and less than 90 °
    An appropriate angle of inclination is adjusted taking into account, notably, the rotation speed of the device.
    According to a possible characteristic, the distributor surrounds a central zone, the pump device being located in said central zone.
    This arrangement makes it possible to accommodate the pump device in said central zone and to make the apparatus more compact.
    It should be noted that the pump device can be partially located in the central zone of the distributor and partially located above or below the distributor according to the desired position.
    According to a possible arrangement, the distributor has an annular shape. The cross section can take different shapes: square, rectangular, circular, etc.
    This shape makes it possible to accommodate at least part of the pump device in the middle of it, as well as other parts, pieces of equipment, fittings, fluidic and electrical connections (cables, swivel joints, etc.), etc.
    In addition, an annular shape is of reduced weight compared to a solid shape, which is advantageous in a rotating device.
    The distributor can be annular in shape and assume the shape of a part of a cylinder of small height compared to its external radius, the intermediate part from which it was removed.
    More particularly, the dispenser may be in a toroidal shape. Such a format proves that it is relatively easy to clean inside.
    According to another possible characteristic, the dispenser has a cylindrical shape.
    The distributor can therefore assume the shape of a cylinder with a small height compared to the external radius.
    According to a possible characteristic, the pump device is located above or below the distributor.
    One of these arrangements can be selected according to the configuration of the system, and in particular, of the other components of it.
    Also, the location above or below the pump device in relation to the distributor can be selected according to the system environment and the space available around the system as well as the arrangement of the other parts of the system equipment and according to the space available around each of them.
    To put it another way, the position of the pump device is merely chosen depending on the space management criteria.
    According to a possible characteristic, each injection medium has a proportional valve to control the volume of liquid injected in the corresponding preform.
    Such a proportional valve which is an optional feature in the system according to the invention may be desired in certain circumstances to control the volume of liquid injected.
    It should be noted that a flow meter can be associated with a proportional valve to provide the liquid flow rate and / or the volume of the liquid injected in each preform.
    In addition, knowledge of the overall volume of liquid injected through a given valve or all valves in the system can be useful.
    According to a possible characteristic, the plurality of molds represents an entire blowing and filling cycle. Thus, in the course of the rotation of the apparatus, each mold containing a preform is subjected to an entire blowing and filling cycle, in particular, it includes blowing and filling with a liquid through the use of stretching and injection means.
    It should be noted that the blowing and filling cycle can also include a closing process or phase during which a lid is attached to a container once the latter has been blown and filled with liquid.
    In this sense, the system may include means of closure.
    According to another possible feature, the system has the ability to simultaneously blow and fill up to 72,000 plastic containers per hour.
    It should be noted that the rotating device of the system keeps turning so that a cycle of blowing and filling a container is not interrupted. BRIEF DESCRIPTION OF THE DRAWINGS

    Figure 1 is a schematic side view illustrating a system for simultaneously blowing and filling containers according to the invention and its main components;
    - Figure 2A is a very schematic overview of the system in Figure 1 that illustrates the entire cycle of blowing, filling and closing;

    Figure 1 schematically represents a system 10 for simultaneously blowing and filling plastic containers, such as bottles, of plastic preforms.
    The system 10 comprises an apparatus 12 which is capable of rotating about a central vertical geometric axis A as indicated by the arrow.
    The rotary apparatus 12 includes a plurality of molds 14a, 14b, ..., 14n, only two of which, 14a and 14b, are illustrated in Figure 1.
    Each mold is a two-part mold that forms an internal cavity 16a, 16b when assembled together.
    A preform that is not shown in Figure 1 is inserted into each cavity at the beginning of the blowing and filling process.
    The shape of the cavity corresponds to the shape of the container reached and it will be completely occupied by the plastic container at the end of the blowing and filling process.
    In the present embodiment, the container is a bottle that is filled with water.
    However, other containers can be considered, as well as other liquids.
    It should also be noted that each mold can alternatively be made up of more than two parts depending on the manufacturing process.
    Apparatus 12 further includes a plurality of injection means 18a, 18b, ..., 18n, only two of which, 18a and 18b, are illustrated in Figure 1.
    These injection means each comprise an injection head that comes in a sealing contact (fluid impermeability) with a preform that has been contained in a mold.
    The injection head includes an injection nozzle that is movable between an injection position that allows the liquid to be injected into the preform and a resting position where the injection nozzle rests on an internal surface of the injection head in a sealing engagement to prevent any flow of liquid from the injection head to the preform.
    Apparatus 12 also includes stretching means 20a, 20b, ..., 20n, only two of them, 20a and 20b, are illustrated in Figure 1.
    Each drawing means comprises a drawing rod which is in sliding connection with the corresponding injection nozzle. Each drawing means is activated by means of the command to be inserted in a preform in order to stretch it while a liquid is injected into the preform to cause the expansion of said preform in the corresponding mold.
    The drive means for driving the rods of the drawing means were not shown in the drawings for clarity.
    Apparatus 12 further includes a liquid dispensing unit or dispenser 22 which is centrally located in the system with respect to the plurality of molds, injection means and drawing means.
    For example, the vertical geometric axis A is a geometric axis of symmetry with the distributor 22.
    The dispenser 22 is operable to deliver a liquid under pressure to the plurality of injection means 18a, 18b, ..., 18n such that the preforms contained in the molds are simultaneously blown and filled by said liquid together with the action of the means stretch.
    As shown in Figure 1, each injection means 18a, 18b (and more generally all injection means up to 18n) is connected to an outlet for the rotary distributor 22 through a fluid duct or pipe 24a and 24b respectively. The plurality of fluid ducts (fluid connections) 24a, b, n are radially arranged as illustrated in the embodiment of Figure 2B.
    For example, dispenser 22 comprises one or several liquid inlets and, internally, is empty to make cleaning easier. The distributor 22 additionally comprises several outlets that are connected to the corresponding ducts or fluid pipes respectively.
    A flow valve 26a and 26b is respectively fitted to the corresponding fluid duct in order to control the flow of liquid between the dispenser 22 and the injection means 28a and b respectively.
    This flow valve is, for example, a proportional valve.
    Such a valve allows the flow of liquid to be precisely controlled and, therefore, for the liquid filling curve (when filling the container together with its blow) to be adjusted to correspond to a given curve.
    Optionally, a corresponding flow meter 28a, 28b, ..., 28n is associated with the corresponding valve 26a, 26b, ..., 26n respectively to measure a flow rate or volume of liquid flowing between the distributor 22 and the corresponding injection means.
    The entire connection between each injection medium and the distributor rotates with these components.
    The liquid to be dispensed and injected is supplied from a liquid source S which feeds a pump device 30 with said liquid.
    The pump device 30 therefore supplies pressurized liquid to the rotary distributor 22.
    In the present embodiment, the pump device 30 is also part of the rotary apparatus 12.
    More particularly, the pump device 30 is operatively connected to the distributor 22 in a conventional manner.
    It should be noted that a flow valve 22 is connected in parallel to the pump device 30 as a safety valve.
    This valve acts as a discharge valve to protect the pump device, for example, when pressure is building up or if there is no flow of fluid to supply (when no bottles are being manufactured).
    The pump device 30 can be located centrally, for example, in a position that is aligned with the vertical geometric axis A.
    This arrangement makes it possible to supply an entire system 10 with a more compact design. This arrangement is also easier to design since the pump device is centered around the rotating geometric axis of the system.
    However, other arrangements of the system can be imagined, in particular, with a pump device displaced laterally with respect to the rotating geometric axis A.
    As shown in Figure 1, the pump device 30 is located above the distributor 22.
    However, in an alternative arrangement, the pump device can be located under the distributor 22.
    In the present embodiment, the dispenser 22 has a cylindrical shape.
    However, other formats can alternatively be considered to deliver liquid to the system's injection media.
    It should be noted that the different rotating parts of the system can be supported by a common rotating plate.
    It will be seen that each mold containing a preform and its corresponding injection means and stretching means forms a station and all of these stations are spatially arranged around the dispenser as schematically represented in Figure 2B.
    Figure 2A is a partial schematic view of the system 10 according to the invention and shows the different operations carried out at each station during the entire manufacturing cycle of a container.
    This cycle includes the blowing, filling and closing phases.
    During the entire manufacturing cycle, each station is subjected to the phases described above.
    As shown in Figure 2A, the distributor 22 of the system 10 is very schematically represented in the central position and different stages of the manufacturing cycle are schematically represented on the periphery of the distributor 22 and indicated by references 40, 42, 44 and 46.
    The stage indicated by reference 40 represents a preform 48 positioned or contained in a mold 50 according to a known manner. Plastic preform 48 was first manufactured using a known molding process and then heated before being positioned in mold 50.
    The preform usually takes the form of a cylindrical tube closed at its bottom end 48a and opened at its opposite upper end 48b.
    Once the preform 48 has been positioned in the mold 50 only the open end 48b of the preform is visible above the mold.
    Stage 40 of the process takes place at a station that is represented by the position P1.
    The P1 position is arranged in a circle C that schematically represents the peripheral line or circumference in which the different stations of the system are spatially arranged around the periphery of the distributor 22.
    Stage 42 illustrates a stage or process step that makes use of a drawing rod 52. The drawing rod 52 is driven to be engaged downwardly at the open end 48b of the preform so as to contact the end closed bottom 48a.
    As shown in stage 42, the drawing rod 52 is then further actuated to push the closed end 48a down and to stretch the preform correspondingly in a controlled manner.
    At stage 42 the stretching process is in progress.
    After the stretching phase has started, the liquid is injected into the preform through its open end 48b, while the stretching rod is still being driven.
    This injection of liquid causes the expansion of the preform together with the movement of the drawing rod until it comes into contact with the inner walls of the mold cavity, thereby reaching the final shape of the container.
    The liquid injection is schematically represented in the next stage 44 by the arrow 54.
    A position denoted P2 illustrates the position occupied by a station at which the blowing and filling process is achieved. In position P2, the container at each station was blown and filled with liquid.
    The blowing and filling process takes place between position P1 and position P2 along peripheral line C.
    The different stations that are arranged between the P1 and P2 positions go through the blowing and filling process that was described above.
    The different stations of the system that are distributed along the peripheral line C between position P2 and P3 (second operating zone; the first operating zone is located between P1 and P2) are subjected to a closing process .
    A lid dispensing unit or lid dispenser 56 is laterally displaced with respect to the plurality of stations arranged along peripheral line C and is more particularly tangent to peripheral line C.
    The cap dispenser 56 includes a plurality of caps 58 which are arranged on the periphery of it and spaced apart.
    More particularly, the lid dispenser 56 takes the form of a rotating device comprising a circular support 60 viewed from above (it supports a substantially cylindrical shape in 3D).
    The lid dispenser 56 further comprises a plurality of housings that are regularly and spatially arranged around the periphery of the support 62 in a manner that may be different from that illustrated in Figure 2A.
    As schematically shown in Figure 2A, the lid distributor 56 further comprises a central element 64 that accommodates the plurality of lids 58 thanks to a plurality of recesses or housings 66 arranged at its periphery.
    More particularly, the peripheral region of the central element 64 can be cut out so as to be formed by a succession of protuberances and cavities in which the lids are housed.
    The central element 64 is attached to the support 62.
    In this embodiment, the entire lid dispenser rotates around its central geometric axis 68.
    However, in an alternative embodiment, only the central element 64 can be rotated while the support 62 remains in its fixed position.
    Thus, the successive covers 58 are distributed successively to the different stations passing through the cover dispenser during the rotation of the system 10.
    Although not shown in Figure 2A, the means for providing lids to the lid dispenser 56 are provided in this embodiment in order to load the lid dispenser 56 with new lids.
    The lids 58 that were distributed to each station passing through the lid dispenser 56 are then positioned above and around the necks of the containers respectively and capped in them in a conventional manner. For the sake of clarity, conventional closing means are not shown in the drawings.
    For example, the lids are screwed around the threaded neck of each container.
    This closing process takes place between the position P3 on the peripheral line C which is located before the cover dispenser 56 and the position P4.
    In position P4, the cap 58 was fixed in the dispensing opening of the container 70 (at present, the container is a bottle). This position corresponds to stage 46 of the process.
    Positions P1 and P4 close a third operating zone in which the molds of the different stations containing a capped and filled container are opened so that the container can be removed before receiving a new preform in position P1 (stage 40).
    It should be noted that when the device spins the liquid it is supplied to the distributor 22 via the pump device 30 and to the different fluid ducts or pipes connected to it. The different valves 26 can isolate the part of the lines connected to the injection means from the distributor by command. Thus, a central processing unit (not shown) that controls the entire manufacturing cycle (in particular, the simultaneous blowing and filling process) can send the control commands to close valves 96 that do not, in due time, involve filling with liquid and open those that were previously closed and, at present, are involved in the filling process.
    Figure 2B is a very schematic top view of a system 80 according to an additional embodiment of the invention.
    System 80 comprises a plurality of stations 90, each of which includes a mold 92 containing a preform or a container according to the stage of the manufacturing process (blowing, filling and closing).
    Each station additionally includes drawing means for drawing the preform contained in the mold. Such stretching means are not shown in Figure 2B for the sake of clarity.
    Each station includes injection means referred to as 94 which are connected through a fluid duct 96 which incorporates a flow valve 98 to a rotating central distributor 100.
    The rotary distributor 100 delivers liquid to each of the above stations.
    The different stations are spatially arranged around the periphery of the distributor 100.
    The dispenser 100 is annular in shape and surrounds a central zone in which a pump device 102 is located. A source of fluid supplying liquid to the pump device 102 is not shown in this drawing.
    In the present embodiment, the pump device 102 also rotates together with the distributor 100 and has an appropriate fluid connection to it.
    As shown in Figure 2B, the pump device 102 has several radially extending arms, for example, three denoted 102a, 102b and 102c which are connected at one end to the pump device and at the other end to an inlet to the dispenser 100 It should be noted that several fluid inlets are used instead of a single inlet in order not to favor a distribution path for a given blowing and filling station.
    The liquid is being sent under pressure by the pump device 102 to the distributor 100 as indicated by the radial arrows. It is more particularly provided for the empty internal space in the distributor 100, through a regular spatial arrangement of the inlets and then distributed to the different fluid ducts 96 connected to each station. Flow valves 98 act as flow valves 26a, b, ..., n in Figure 1 and control the flow of fluid from the dispenser 100 to each of the injection means according to the process stage. For example, valves 98 are commanded to open when the filling stage is being carried out.
    Only a few stations 90 were represented in Figure 2B at different stages of the entire blowing, filling and closing process.
    The angular position of each stage represented in Figure 2A is the same as in Figure 2B.
    After position P4, the next station illustrates the opening of the mold 90 to successively remove and eject the blown, filled and capped container and to introduce a new preform therein.
    System 80 also comprises a lid dispenser as in Figure 2A, but which has not been represented here for the sake of clarity.
    It should be noted that this cover dispenser does not rotate with the rotating parts of the system 80, it only rotates around its own geometric axis.
    However, in a variant mode, the cover dispenser can be part of the rotating device in the system.
    Figure 3 illustrates another embodiment of a system 120 according to the invention.
    System 120 comprises the same components as those illustrated in Figure 1. Although for each piece of equipment the references a and b have been used, (for example, 14a and b, 26a and b, etc.), it should be understood that the system also includes references to n.
    For the sake of ease, all the different components of system 120 have the same references as those of system 10 in Figure 1.
    The different characteristics and advantages established with respect to system 10 are the same for system 120 in Figure 3 and, therefore, will not be repeated.
    The difference between system 120 and system 10 is that the plurality of stations is inclined with respect to the central vertical geometric axis A around which the entire system rotates, while in Figure 1 the different stations extend each to the along a geometric axis that is parallel to geometric axis A.
    More particularly, in Figure 3 each mold 14a, 14b extends in a longitudinal direction that is in alignment with the longitudinal geometric axis a, b respectively.
    All other stations not shown in this drawing have the same orientation.
    The mold 14a, 14b has an opening 15a, 15b which is provided at the top of the mold.
    A preform with a mouth that is not shown in Figure 3 must be inserted into the mold and more particularly through the opening 15a, 15b so that the mouth of the preform protrudes from the mold.
    The opening 15a, 15b is respectively centered around the longitudinal geometric axis a, b which is inclined towards the central vertical geometric axis A.
    More particularly, the longitudinal axis a, b is at an angle α with respect to the vertical axis that extends between 0 ° and 90 ° and that is, for example, 45 °
    This inclination towards the central vertical geometric axis A makes it possible to avoid splashing liquid throughout the container during the rotation of the entire system thanks to the centrifugal forces exerted on the moving liquid.
    It should be noted that the angle of inclination has to be appropriately selected according to the rotation speed of the system and its diameter. To put it another way, the angle depends on the tangential rotation speed of the stations.
    A system according to the present invention has the ability to simultaneously blow and fill an amount of plastic containers up to 72,000 per hour.
    It should be noted that the closing process is also included in this high operational productivity.
